The Characterization of Haze and Dust Processes Using MAX-DOAS in Beijing, China [PDF]
Remote Sensing, 2021 Haze and dust pollution have a significant impact on human production, life, and health. In order to understand the pollution process, the study of these two pollution characteristics is important. In this study, a one-year observation was carried out at the Beijing Southern Suburb Observatory using the MAX-DOAS instrument, and the pollution ...

Ground-Based MAX-DOAS Observations of CHOCHO and HCHO in Beijing and Baoding, China [PDF]
Remote Sensing, 2019 Glyoxal (CHOCHO) and formaldehyde (HCHO) trace gases were successfully retrieved from a multi-axis differential optical absorption spectroscopy (MAX-DOAS) system in Beijing (39.95°N, 116.32°E) and Baoding (39.15°N, 115.40°E), China. The measurements of these trace gases span the period from May 2017 to April 2018.
